摘　　要：塔东古城地区碳酸盐岩储层具有物性差、纵横向非均质性强的特点,识别白云岩是提高勘探成功率的关键.首先,根据钻井资料建立了白云岩储层的地质模型,并通过模型正演分析了地震波动力学属性参数的响应特征;然后,基于储层标定和正演模拟分析建立了白云岩储层的地球物理识别模式,为储层识别、预测提供了依据.通过“甜心体”预测了白云岩储层发育带,建立的基于地震正演模型识别白云岩储层的方法行之有效。The carbonate reservoirs in East Tarim Basin are characterized by poor physical properties,and strong anisotropy in both vertical and horizontal directions,so how to recognize the dolomite is the crucial for enhancing the success rate of the exploration in the area.Firstly,based on the well-drilling data,the geological model is established for the dolomite reservoirs,and moreover through the model forward,the response characteristics of the common-used seismic-wave dynamic parameters are analyzed,and then on the bases of the reservoir calibration and forward modeling,the geophysical recognizing mode of the dolomite reservoirs is established,thus the evidences for the providing the support for the reservoir recognition and predication are presented.Utilizing the ＂sweet spot body＂,the well-developed dolomite reservoir belts are predicated.The method established by the seismic forward model to recognize the dolomite reservoirs is proven to be practical and effective.
